Step 1
Move a (magnetic/plotting) compass around the wire
Answer
To demonstrate that a magnetic field has been produced around the wire, move a magnetic compass around it. The compass needle will change direction, indicating the presence of a magnetic field.
Alternatively, you can use this method:
- Tap a card containing iron fillings onto the wire. This will cause the iron fillings to align along the magnetic field lines, visually demonstrating the magnetic field pattern.
